Thermoplastic composition comprises: a matrix material made of a polypropylene-based elastomer with an amount of polyethylene. The weight ratio of polypropylene to polyethylene is 95:5-75:25. An amount of expandable graphite and an amount of at least a flame retardant are embedded in the matrix material and optionally at least one further regular additive is embedded in the matrix material, or mixed in insulating layer-forming thermoplastic composition. Independent claims are also included for: (1) an insulating layer-forming building material comprising the above thermoplastic composition; and (2) a use of a thermoplastic composition for producing an insulating layer-forming building material, comprising extruding the thermoplastic composition using a nozzle working according to the fish-fin principle or coat-hanger principle, to form a molded body, preferably a tape, a strip, a plate, a sleeve or a winding tape or introducing the composition in a molded part, preferably a collar molded part. |
